The Makita 18-Volt LXT Lithium-Ion Brushless Cordless 1/2 in. Driver-Drill Kit (XFD12T) is an ideal drilling and driving solution for the user who wants a drill with superior power-to-weight ratio. The XFD12T combines 530 in. lbs. of Max Torque with an efficient brushless motor that delivers up 50% more work per charge, increased power and speed and longer tool life. For the pro user this means more drilling and driving power, greater productivity and fewer trips up and down the scaffolding or ladder to get to the battery charger. In driver mode, the adjustable torque settings provide more control for a full range of applications, from large fasteners to smaller, delicate screws. It weighs only 3.9 lbs. (with 5.0Ah battery) for increased comfort and superior power-to-weight ratio. The XFD12T is compatible with Makita 18-Volt LXT Lithium-Ion batteries, from the fast-charging 18-Volt LXT Compact 2.0Ah battery to full-size 18-Volt LXT batteries for longer run time. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18-Volt LXT and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
